Abstract (en)
[origin: EP2360403A1] The drive (100) has a hand actuating element i.e. hand wheel (130), coupled with a shaft (120), and an overload clutch (140) arranged between the hand actuating element and the shaft. The overload clutch limits torque transferred from the hand actuating element to the shaft. The overload clutch comprises a coupling element (142) and replaceable spring elements i.e. laminated springs (148a-148c), which are partially made of metal. The replaceable spring elements press the coupling element against the shaft, so that a maximum valve for the transferred torque is based on the spring elements.
